A tip for those using a Bridge and wanting to shorten the ridge line (real or virtual) to fit better under a tarp.
The easiest way to do this is to use a shorter spreader bar on the foot end. You can also then shorten the suspension triangle sides. The best to figure the new foot end suspension triangle sides is to use the same angles as on the head end. Use similar triangles to get the new dimensions. Grizz knows the BMBH dimensions and can probably help. If you want you can post the dimensions of your head end suspension triangle here and my GF or TeeDee can do the figuring.
By using a shorter foot spreader and similar triangles, TeeDee cut our ridge line length from 118" to 107". That 11" shorter length made a lot of difference under the tarps. Even a 9' long tarp works well now and covers the whole ridge line.
